Mainly with the "ad", because that article is about the book, not the actual interpretation that might be insightful (or not) in some way.

Besides, much of Nietzsche's late work was indeed rambling, the guy was severely depressed, even mad at the end. It doesn't discredit his entire work, but that fact must be kept in mind dealing with it. His (even crazier) sister publicized some of his works that never were intended by him to reach public. But they did, and then Nazis happened. So, the issue is also that it's an another interpretation of Nietzsche's work.
